Abstract: A method of location information in a mobile device capable of improving position accuracy of the mobile device using a database (DB) of peripheral auxiliary data when GPS and navigation are performed in the mobile device, and an apparatus thereof is provided. The method of providing location information in a mobile device includes acquiring initial location information of the mobile device when a location based service is executed, transmitting the acquired initial location information to a server, receiving auxiliary data corresponding to the initial location information from the server, classifying satellites to be used to determine a location with reference to the auxiliary data, and determining the location based on a satellite signal of a satellite having a high weight through the classification of the satellites.

Abstract: A movable electronic device for providing location information to an external electronic device includes: at least one sensor; a satellite-positioning circuit; a communication interface; and a processor functionally connected to the at least one sensor, the satellite-positioning circuit, or the communication interface. The processor is configured to identify that the electronic device is in a fixed state, identify whether a predetermined time elapses from the identification based on the identification, determine absolute coordinates of an area in which the electronic device positioned using a plurality of signals received from at least one satellite for the predetermined time from the identification based on identification of the elapse of the predetermined time, and transmit information on the determined absolute coordinates to the external electronic device. The transmitted information on the absolute coordinates is used to determine absolute coordinates of an area in which the external electronic device is positioned by the external electronic device.
